OPA188AIDR Description

Short technical summary and product information.

The Texas Instruments OPA188AIDR is a single-channel, zero-drift operational amplifier designed for high-precision applications. It features extremely low offset voltage (25 µV max) and offset drift (0.03 µV/°C typical), making it suitable for systems requiring stable and accurate performance over temperature variations.

 

This amplifier boasts low noise characteristics with 8.8 nV/√Hz at 1 kHz and 0.1-Hz to 10-Hz noise of 0.25 µV PP. It offers a wide supply voltage range from ±2 V to ±18 V and features rail-to-rail output capability, allowing for maximum dynamic range. The input stage includes negative rail capability and RFI filtering for enhanced robustness.

 

Key electrical specifications include a gain bandwidth of 2 MHz, a slew rate of 0.8 V/µs, and high DC precision with a CMRR of 146 dB and PSRR of 142 dB. The quiescent current per channel is typically 0.425 mA, with a maximum of 510 µA. The OPA188AIDR is available in SOT-23, SOIC, and VSSOP packages, all suitable for surface mounting.

 

Its combination of precision, low noise, and wide operating range makes the OPA188AIDR ideal for various analog signal processing tasks, including sensor conditioning, active filters, and medical instrumentation.
